However, the Married at First Sight UK experts started to notice that conditioning coach Franky, 47, could be quite closed off, and during a dinner party, he got quite rude with Marilyse.
Nevertheless, the pair managed to make it to the end of the experiment, and made their final vows on Wednesday 29th September.
But, what did they decide?
Here's everything you need to know about Marilyse and Franky and whether they're still together.
Who is Marilyse?
Job: Personal trainer
Marilyse is an elegant, sporty lass from Yorkshire. She works as a personal trainer and leads a very fitness-dominated lifestyle, and she's looking for a man to match this same energy.
Her dream was to find her teammate in life, who she can conquer the world with! They’ve just got to get her two sons’ approval first, who are keen for their mum to be with someone, but they have a lot of thoughts on who that should be.
"I would love to go through to the experiment to the very end and still be with the guy. That is what I want to happen and what I expect to happen. I will be a bit disappointed if it doesn’t happen, but we’ll have to wait and see," she said.

Who is Franky?
From: Currently living in Dubai
Job: Strength and conditioning coach
Franky is a 46-year-old strength and conditioning coach. He currently resides in Dubai, and hoped his new parter would join him overseas. Prior to his move across the pond, Franky was part of the military.
He desperately wanted to find someone who shares his morals and his beliefs.
"All my life has been about challenges. I don’t like to do the normal. If anything is normal then I find it boring. I’m not captured unless I’m entertained and challenged – and Married At First Sight UK is a bloody big challenge," he said in an interview before his MaFS debut.

Are Marilyse and Franky still together?
Marilyse and Franky decided to stay together at the end of the experiment.
Viewers will have wait to see if things worked out once the cameras stopped rolling on the Married at First Sight reunion, airing on Monday 4th October.
But, so far so good, with the couple leaving the show as a married couple.
Marilyse and Franky got on well from the start, however, during one of the dinner parties, Franky was very rude to Marilyse and told her not to speak while he was. She stood up for herself and warned him about speaking to her in that tone, and he apologised. The experts later questioned him about this attitude, but Franky chose not to open up to them.
Their homes stay went well, with Franky revealing to Marilyse that he wanted to move back to the UK for her. She wanted to make sure he was doing this because he definitely wanted to, at which point he insisted it was only right, with Maz having two teenage sons.
Both Marilyse and Franky have been sharing cute snaps on their social media pages, which could mean they're very much still together.
